A 66year-old man with sustained fever was diagnosed as having acute myeloid leukemia with multilineage dysplasia. Induction therapy with etoposide and AraC was initiated, but was ineffective. Although fever had persisted for more than a few days, there was no evidence of any infection on radiological examination or culture studies. The patient was disorientated and demonstrated personality change. After a severe convulsive seizure, the patient died. Autopsy findings showed that the leukemic cells had permeated the Virchow Robin space, but without a mass lesion in the cerebral parenchyma. He was diagnosed as having had central nervous system leukemia (CNSL) that provoked sustained fever, consciousness disturbance and convulsive seizure. These findings suggested that the Virchow Robin space plays a particular role in the development of CNSL. Even with repeated cerebrospinal fluid examinations and radiological tests, we were unable to correctly diagnose CNSL before death, which may indicate the intractability of diagnosing CNSL spread along the Virchow Robin space. This case provides useful information about the pathophysiology and diagnosis of CNSL.

A 24-year-old woman was hospitalized with seizures in 2002. Magnetic resonance imaging demonstrated an intraspinal mass and inhomogeneous gadolinium enhancement along the cerebrospinal meninges. Cerebrospinal fluid (CSF) cytology showed large atypical cells expressing CD2, cytoplasmic CD3, CD7, CD13 and CD30. The patient was finally diagnosed with primary central nervous system anaplastic large cell lymphoma (ALCL). She completed 5 courses of methotrexate (MTX)/ procarbazine (PCZ)/ vincristine (VCR) (MPV) chemotherapy, followed by 2 courses of high dose cytarabine (AraC) and achieved a complete remission. In 2003, she suffered from headache. CSF analysis showed atypical lymphoid cells expressing CD 30. First CNS relapse was diagnosed. She then underwent autologous peripheral blood stem cell transplantation (auto-PBSCT) after administration of thiotepa, buslfan, and cyclophosphamide. However, second CNS relapse occurred in 2004. She received 5 courses of MPV chemotherapy followed by 36 Gy of craniospinal irradiation. Although there was no recurrence of the CNS disease, a third relapse was detected in the right breast in 2009. Pathological and immunohistochemistry analysis revealed ALK-1 positive ALCL. She was treated with 6 courses of cyclophosphamide/adriamycin/vincristine/predonine (CHOP) chemotherapy and 30.6 Gy of local radiation therapy. She has remained in remission for 6 years, to date, since the last therapy and has an excellent quality of life.

Superior sagittal sinus thrombosis (SSST) is a very rare but life-threatening complication in leukemia patients. SSST is very rare in acute myeloid leukemia (AML). In leukemia patients, several risk factors for SSST have been reported such as administration of L-asparaginase, disseminated intravascular coagulation, congenital thrombophilia, meningeal leukemia, and intrathecal chemotherapy (IT). Lumbar puncture itself and corticosteroid administration have also been acknowledged as risk factors. We describe herein our clinical experience with SSST in a 29-year-old Japanese man suffering from AML with t(8;21)(q22;q22), who presented with abrupt onset of loss of consciousness, left hemiplegia, and seizure soon after IT and high-dose cytarabine (HD-AraC) with dexamethasone for post remission consolidation. Despite the presence of intracranial hemorrhage (ICH) due to SSST rupture, we conducted anticoagulant therapy with heparin. Although ICH worsened temporarily, his clinical condition gradually improved with resolution of the SSST, and he eventually became fully ambulatory. There were no deficiencies of natural anticoagulants. Three additional cycles of HD-AraC without IT therapy were conducted, but no neurological complications recurred with the concomitant use of warfarin. He was discharged free of neurological deficits. In our case, there is a possibility that IT and the administration of corticosteroids along with HD-AraC triggered SSST.
